the fundamental elements of nature, namely earth, water, air and sunshine should be in a healthy state, well balanced with the criteria of equilibrium and untainted so that the environment would remain pleasant and lively. hence, there will be plant, animal and human in a existential balance. man himself is the major polluter and destructor of environment. the environment, in turn, is a large c...

An offi cial committee now ponders the question of whether human impacts have derailed the Earth system suffi ciently to declare the beginning of a new geological epoch, the Anthropocene. Meanwhile, researchers have updated and improved two infl uential assessments of our global status, namely the ‘planetary boundaries’ and the ‘great acceleration’ graphs. Michael Gross reports. Assessing human...

Heparin is an injectable anticoagulant that prevents coagulation. There are presently high and low molecular heparins as well as synthetic pentasaccharide inhibitors. Given its ubiquitous use in sensitive medical states, there is a high concern for safety with this drug. Heparin can induce several distinct immune-mediated reactions. There are several options to consider when heparin allergy occ...

Late-preterm newborns accounted for 8.7% of all US births in 2009, while in Italy, according to Euro-Peristat Report 2010, rate of preterm live births between 32 and 36 weeks accounts for 6.4%: therefore late-preterm incidence is around 5% [1]. In the literature is reported that late preterm infants are at increased risk of neonatal mortality and morbidity, including feeding problems, hyperbili...

X-ray absorption and magnetization experiments are used to describe the oxidation states of the rare earth ions R=Ce, PI and Tb in the double layer high-Tc superconducting series RBa2Cu307 and Pb2Sr2R1-,CaXCu3O8. We obtained the same oxidation states for the rare earths in these two classes of compounds, namely, R=Ce tetravalent and R=Pr and Tb trivalent.
